CVE-2023-53193: 
Linux Kernel vulnerability analysis and mitigation

A vulnerability was identified in the Linux kernel's AMD GPU driver (CVE-2023-53193), discovered and disclosed on September 15, 2025. The issue specifically affects the drm/amdgpu component, where the amdgpuirqput function in gmcv100hwfini causes an unnecessary call trace due to firmware privilege restrictions (NVD).

The vulnerability stems from a mismatch between firmware and driver privileges regarding interrupt handling. The gmc.eccirq is enabled by firmware per IFWI setting, and the host driver lacks the privileges to enable/disable the interrupt. This leads to an inappropriate use of the amdgpuirqput function in gmcv100hw_fini, resulting in a call trace in the system (NVD).

The vulnerability can cause system instability through kernel call traces, potentially affecting system operations using AMD GPU drivers. Most major Linux distributions have marked this as not affecting their current releases, suggesting limited real-world impact (Ubuntu).

Major Linux distributions including Ubuntu have evaluated this vulnerability and marked most of their releases as 'Not affected'. This suggests that either patches have been applied or the vulnerable code is not present in current releases (Ubuntu).
